Offhand, only anecdotal. For much of the last decade, I have done production sound for film and video. I generally use Schoeps microphones, which cost a couple of thousand apiece (just so you know cost isn't a factor here). The reason I prefer MDR7506s is that when I'd set up every day, they're the only headphones that sound the same when I put them on as when I take them off.
